Answer:
22 sides
Step-by-step explanation:
The expression to find an interior angle of a polygon is:
The expression to find an exterior angle of a polygon is:
Please note that "n" represents the number of sides the polygon has.
We can use these two expressions to set up an equation.
Multiply both sides by "n":
Now, distribute:
Divide both sides by 10:
Add 36 to both sides:
Divide both sides by 18:
The polygon has 22 sides
227.5 You multiply it be 1.3, so you can add on the extra 30%
The formula for a discriminant is b^2-4ac
so, (-7)^2 -4(3)(6) simplifies to 49-72 which equals -23
First, you need to see which number all of these numbers have in common, and that is number 4. So, let's start:
-4(x2 - 4x + 6)
The expression in the brackets cannot be factored further, which means that the answer above is the complete factor of the original expression. Hope it helps. :)
I = PRT
P = 300
R = 0.14
T = 2
now it is just a matter of subbing and doing the math
I = (300)(0.14)(2)
I = 84 <==
